Rise & Fall occurs in cycles, typically cycles of 3 or 4 steps (with certain exceptions). Many of the basic figures of Quickstep use a 4-step cycle, such as the Quarter Turn, Progressive Chasse (to left and right), Forward & Backward Locks, etc. These are figures where the lowering doesn't take place until the end of the fourth step, and so the footwork of the fourth step itself is toe-heel.

Some figures in Quickstep, however, use a 3-step cycle of rise & fall, similar to the Slow Waltz basic natural & reverse turns. Any Quickstep figure that incorporates 1-3 Natural Turn, such as a Natural Turn, Natural Turn with Hesitation, Natural Pivot Turn and Natural Spin Turn will use a 3-step cycle, where the lowering is done on the end of the 3rd step. The Chasse Reverse Turn and Cross Chasse also fall into this category. In these cases, the 4th step is taken with a heel lead by the person moving forward.

There's no hard and fast rule as to which figures you can expect will use which cycle -- some rise and lower over an odd number of steps, such as the Tipple Chasse, which has a 7-step cycle. You could probably guess with a high degree of success simply by looking at the number of steps in the figure, not counting any "overlaps" (the steps that say "as first step of following figure"). Figures of 4 steps *generally* use a 4-step cycle, while figures of 3 or 6 steps *generally* use a 3-step cycle. But this isn't always the case.

The Cross Chasse, however, does follow this pattern. If you are aware that the 4th step in the figure is really an "overlap" -- the first step of the following figure -- then you'll recognize it as a 3-step figure, and therefore as having a 3-step cycle of rise & fall. Lowering at the end of the third step, you would naturally take a heel lead as you step forward on your right foot to begin the next figure.
